RAILROAD JOINT.

Application led June 14, 1927. Serial No. 198,775.

The invention forming the subject matter of this application relates to railroad joints.

An object of the invention is to provide a railroad joint in which the joint is formed by the` ends of the rails themselves Without necessitating any bars to: reinforce the same.

Another object of the invention is to provide identically beveled rail ends which form an uninterrupted continuity of rails and which are substantial and strong enough to prevent the separation of the rails, but permit sufficient clearance between the rail ends to provide for the expansion of said rails.

A still further object of the invention is to provide overlapping rail ends Which are adapted to carry the same or more load than any of the present rail joints in use and which eliminate the use of the reinforcing plates such as lish plates.

The above and other objects in vieW Will more readily appear as the description pro ceeds.

Although We show and describe a preferred form of the invention it is to be understood that changes as to the form, parts and arrangements thereof may be made Within the scope of the claims, Without de parting from the spirit of or' sacriiicing any of the advantages of the invention.

In the accompanying one-sheet of drawins,

Figure 1 is a perspective View of the rail joint,

Figure 2 is a perspective vieiv of one of the rail ends,

Figure 3 is a section taken through the approximate horizontal center line of the rail joint,

Figure 4 is 4a cross section talren along the line 4 4 of Figure 3.

ln carrying out our invention We provide rail ends l and 2 shoivn in Figure l, said rail ends to be identical, therefore the description of one of said rail ends explains the design and the function of both rail ends. The rail end 1 is beveled from the point 3 to the end of the rail. Along the central portion of the beveled end, the inner surface thereof is straight fr'om the points 4 to the end of an extension 5. Said straight face of the extension 5 is in alignment With the outside face of the web 6 of the rail. In order to provide suflicient material to reinforce the end of the rail cut in said beveled shape a Web flange 7 is provided eX- tending from the end of the extension 5 to substantially inside of the point 3. The outside `face of said web flange 7 is parallel with the outside face of the web 6, thereby providing increasing reinforcing thickness from the end of the extension 5 to beyond the other end of the bevel cut. Squared shoulders 8 and 9 are cut respectively on the base flange and head flange of the rail at approximately the end of said bevel in order to form an abutting surface for the ends of the adjoining rails. Elongated holes 10 are spacedly disposed in the beveled end of the rail to receive bolts 1l holding the opposite rail ends together. Although the bevel eX tends on the rail to the shoulders 8 and 9 the horizontal central portion thereof from the points 3 is cut straight in a line with the inside surface of the Web 6 thereby forming an indentation therein to receive the extension 5 of the other rail. The inside surface of the extension 5 is straight from the points et, said points 4: being inside of the end of the rail. Thus the extension 5 protr'udes from the face of said bevel said protrusion to correspond With the indentation on the opposite end of the bevel, as it is clearly shown at l2 on Figure 4.

The forming of a railroad joint now involves simply the sliding of the beveled portions of the rails together so that the extensions 5 slide into the indentations on the bevels and the elongated holes l0 are brought in registry with each other so as to permit the bolts ll to be passed there through. After the bolts are tightened up a lirm joint is formed and the ends of the rails are prevented from moving up or downwardly relative to each other because of the extension 5 and the indentation in the bevel. The longitudinal slipping of said rails is permitted only to the extent of the possible expansion of the rails.

The advantages of the invention consist in reducing the number of Working parts and the simplicity of the assembling of a joint. The strength of the railroad joint heretofore described stands up under any circumstances and eliminates all parts Which may Work loose under heavy duty.

Having thus described our invention, what We now claimV as novel and desire to secureby Letters-Patent is: Y

` l. In a rail compris/ing a Vbase flange, a Web, anda head flange, aligning shoulders squared on one side of said head flange and base flange and disposedat a distance from the end of the rail; a longitudinally tapered face extending from said shoulders to Vtheing flange extending in'continuation of' said tapered Web face to the extremity Vof said reinforcing flange, thereby forming a pro! trusion on said tapered face having continuations of said tapered face on either side of it to the end of the rail, another straight surface extending in continuation of the inside endl of said tapered web face, forming a complementary indentation at said inside end of said tapered web Jface and between said head flange and base flange.

2. In a rail comprising a vbase flange, a

fweb, and a head flange; aligning shoulders squared on one side of said head ange and base flange and disposed at a distance from the end of the rail; a longitudinally tapered face having head and base portions and a web portion; said head and base portions of said tapered face extending from said shoulders to the end of the rail, said mediate web portion of said tapered face being shorter `than said head and base portions, the extremities of said mediate. Webr taper being eqiiidistant from' said vshoiilderandV said rail end; the unijeduced mediate Web portions in continuation of saidweb taper forniinff a irotriision in the natnre of a Wide rib extending gradually fronithe surfaceof` said tapered face at thethin end and a coinpleinentai'y indentation at the thick end of said reduced face.
